ABSTRACT
In the capacity design procedure of ductile open frames, the columns couldnotbe designed before the beams are designed. This is not practical in the real world of design practice. In the previous study, several alternatives allowing partial side sway mechanism were proposed. In the proposed method, the perimeter columns of the reinforced concrete frames were designed to remain elastic for a certain seismic load level. In this study a refined method is proposed. Three symmetrical of six, eight and ten story fully ductile open frame buildings are designed in accordance to the new Indonesian Earthquake Code (SNI-03-1726-2002) using the proposed method. The seismic performances of these buildings are evaluated using three dimensional static pushover analysis. The results are then compared with the outputs of three dimensional non-linear time history analysis.
